Raw Normal View History

feat(theseus/screenshot): 0.5.0 — sidebar-first editor, direct save/copy, sounds Two problems the old editor kept hitting: - __pending drain race: opening the editor a second time (refresh, back-and- forth navigation) found the storage entry already consumed and bailed to a blank canvas silently. - Cross-origin img loading: editor.html at file:///…/addons/screenshot/ loading a scratch PNG at file:///…/addons-data/ counts as cross-origin under Chromium's file-URL policy; setting crossOrigin="anonymous" made the load fail outright. Rebuilt editor v2: - Load path is idempotent: silentmode.invoke("getBytes", {name}) → addon reads the scratch file and returns a data URL. No __pending drain, no cross-origin trickery — data: URLs are same-origin and never taint the canvas, so getImageData / toBlob keep working. - Two-canvas model (#base + #over, over is pointer-events:none) so live previews don't cost a full re-composite per mousemove. - Tools: cursor, arrow, rect, ellipse, pen, text. 6 swatches, 3 widths, undo / redo (25-deep). Copy + Save at the top bar. Back and Maximize buttons in the same top bar so navigation controls stay reachable when the toolbar wraps at narrow widths. - Keyboard: A/R/O/P/T select tool, Esc = cursor, Ctrl+Z/Shift+Z undo/redo, Ctrl+S save, Ctrl+C copy. - Toast surface for save/copy/error feedback. Sidebar panel gains a direct raw-save path so the user can copy or save the capture without entering the editor: - Two-row actions: [Copy] [Save] on top, [Discard] [Edit] below. - Copy uses navigator.clipboard.write(ClipboardItem); Save uses <a download> with a Blob URL — same path Chromium's will-download tracker already handles, so the file lands in Downloads and the chip updates like any other save. Inline "clear all" confirmation replaces the native confirm() — the old system-modal opened over the tab area (out of the sidebar's visual context) and looked like Windows 95. Now a compact red strip appears under the Recent header with Cancel / Delete buttons. Sounds + a sound-on/off toggle in both surfaces: - Web Audio oscillator-synthesized (no .wav shipped): shutter click on capture, two-tone bloop on copy, descending pair on discard/back, ascending triad on save. - Preference stored in silentmode.storage under "soundOn" (default on), shared between the panel and the editor. Simplifications: - Dropped the addon's "arm" onMessage handler (superseded by getBytes). - Manifest capabilities: sidebar-panel + capture-tab (no open-tab, no toolbar-menu). Bundled but not shipped — parent session handles the OTA sign + push.
